Volcano Erruption

An except of how volcano research and monitoring can save lives

By Adejuwon Soyinka.

Volcanic eruptions come with a variety of hazards, depending on the type of volcano and its magma. Some have effusive eruptions, where lava flows constantly, while others can expel large clouds of fragments of magma and gases – volcanic ash – into the atmosphere. For some of the most powerful eruptions, these ash clouds can rise tens of kilometers into the air and travel thousands of kilometers. This is what has happened on the island of St Vincent and the Grenadines, after a new eruption was confirmed at La Soufriere volcano on April 9 2021. The explosive eruption, the first since the volcano last erupted in 1979, produced an ash plume of about six kilometers, which was also seen in satellite images. The eruption prompted the evacuation of about 20,000 people, with no casualties. This was made possible thanks to our improved understanding of how volcanoes work and new advances in volcano monitoring.
